Just tried the following code, it works :) Only change is that I don't
use the variable $key!
[code]
$hashCode = mhash(MHASH_SHA256, 'ENCRYPTIONISAGOODTHING',
true);
pr($hashCode);
[/code]
Or now that I look at it, maybe that your are using $key both as input
and output! Check it out! :)
Enjoy,
John
